Definitions

  • the present invention has for object an exerciser comprising at least one movable element on which acts the user for moving it against the action of an antagonistic force.
  • this antagonistic force is not constant and increases with the displacement of the movable member on which acts the user of the apparatus.
  • the object of the present invention is to furnish an apparatus of the above mentioned type in which the antagonistic force against which acts the user of the apparatus remains substantially constant during the operation.
  • FIG. 1 is a perspective view of an exerciser.
  • FIG. 2 is an elevational view, to a larger scale and with a sectional portion, of the apparatus according to FIG. 1.
  • FIG. 3 is a lateral view thereof, with a partial section, to the scale of FIG. 2.
  • FIG. 4 is a sectional view on the broken line IV--IV of FIG. 3, to a larger scale.
  • FIG. 5 is a sectional view on the line V--V of FIG. 4, to a larger scale, some portions being broken, and
  • FIGS. 6 to 9 are sectional views of a detail of four modifications.
  • the apparatus represented in FIGS. 1 to 5 comprises a vertical column 1, of square section, which can be secured to a wall, comprising, at its basis, a seat 2 on which is seated the user, and carrying, above this seat, a padded portion 3, constituting a back.
  • the column 1 is mounted on a basis member 4, resting on the ground, provided with a transversal member 5 constituting a foot-rest.
  • the apparatus comprises, moving in the column 1, a cylinder 6 provided with rollers 7 arranged diagonally, as specially shown in FIG. 4, guiding the cylinder 6 in its displacements in the column 1.
  • This cylinder is rigid with two control arms 8 which are gripped by the user of the apparatus when it is seated on the seat 2 and that he moves downwardly.
  • These two arms 8 are articulated on forks 9 which are themselves secured to the cylinder 6 and which moves themselves in slits 10 provided in the lateral walls of the column 1.
  • the articulation of the arms 8 on the forks 9 is arranged in such a way as to permit the orientation of the arms 8 being adjustable on about 90° in the sense of the arrow 11 of FIG. 4, and being blockable in this position.
  • the basis 6a (FIG. 5) of the cylinder 6 is provided with an aperture through which passes a rectilinear tube 12 opening in the room provided by the cylinder 6, secured to a mounting member 13 itself secured to the bottom, designated by 14, of the column 1 and which is connected by a duct 15, to a compressor 16 located under the seat 2.
  • This compressor permits to create in the tube 12 and the room 6 a pressure which is higher than the atmospheric pressure.
  • a duct 17 passes through the basis 4 and ends to a manometer 18 (FIG. 1) situated above the rest-foots 5 which permits to the user of the apparatus to know the pressure reigning in the room 6.
  • the tightness between the bottom 6a and the tube 12 is obtained by an annular gasket and by an oil bath 19 situated in the bottom of the room.
  • the pressure reigning in the room has for effect to oppose itself to the downwards displacements of the cylinder 6 by a force which is function on the one hand of the said pressure and on the other hand of the section of the tube 12.
  • the penetration of the tube 12 inside the room 6 produces only a very low increase of the pressure inside the room since the volume of the portion of the tube 12 engaged in the cylinder 6 is low with respect to the total volume under pressure.
  • the antagonistic force the user of the apparatus has to overcome when he acts on the arms 8 of the apparatus for displacing the cylinder 6 downwardly, indicated by the arrow 20 of FIG. 5, is substantially constant, increasing only neglictably during this displacement.
  • This antagonistic force is adjustable as the user wants it, since the user can vary the pressure reigning in the room 6.
  • FIG. 6 distinguishes from the embodiment of FIGS. 1 to 5 by the fact that, in the latter, the cylindrical room, designated by 22, is stationary in the column, designated by 23, of the apparatus, the control arms being rigid with a bar 24 which passes through the upper axial face, designated by 22a, of the room 22 and penetrating into the latter.
  • the bar 24 can be full or hollow, the total volume under pressure being, in the latter case, increased, that has for advantage of reducing the slight increase of the pressure when the bar 24 is moved downwardly by the user of the apparatus.
  • the cylinder 22 is provided, at its basis, with a pipe 25 intended to connect it to a compressor.
  • FIG. 7 distinguishes from this of FIG. 6 by the fact that, in order to still increase the volume under pressure, the cylindrical room, designated by 26, in which moves the vertical bar 27 submitted to the action of a control member 28, is in communication with a second room, designated by 29, provided with a pipe 30 intended to be connected to a compressor.
  • the antagonistic force remains substantially constant, by reason of the increase of the volume under pressure, even when, in this case, the cross section of the bar 27 corresponds substantially to this of the cylinder 26.
  • FIG. 8 The modification of FIG. 8 is similar to this of FIG. 7 with the difference it is not the bar diving in the cylinder which is movable, but the cylinder, designated by 31, which slides on the bar, designated by 32, which is hollow.
  • the hollow bar 32 is in communication with a second room, designated by 33, corresponding to the room 29 of FIG. 7.
  • the cylinder room, designated by 34 is traversed by an elongated member comprising on the one hand a hollow portion 35 and on the other hand a full stem 36, a passage 37 making the inner duct of the hollow portion 35 to communicate with the inner of the room 34.
  • the antagonistic force opposing itself to the displacement of the cylinder 34 downwardly is function on the one hand of the pressure inside this cylinder and on the other hand of the difference between the cross sections of the portions 35 and 36 of the member traversing the cylinder 34.
  • the cylinder 34 could be secured to the movable member 35-36.
  • the compressor may be replaced by a bottle of gas under pressure or by a foot pump.
